A) 2⁻² + 4⁻²/2⁻⁴ + 4⁻¹ = 1/2² + (1/4²)/(1/2⁴) + 1/4¹ =
1/4 + (1/16)/(1/16) + 1/4 = 1/4 + 1 + 1/4 = 2/4 + 1 = (2 + 4)/4 = 6/4 = 3/2
b) -3/8⁻² = -(8/3)² = - 64/9
c) a² . a⁵ . a¹ = a⁽²⁺⁵⁺¹⁾ = a⁸
d) 10⁸/10³ = 10⁽⁸⁻³⁾ = 10⁶
e) (a⁻⁵)⁻² = a⁽⁻⁵ˣ⁻²⁾ = a¹⁰
f) (2³)² . 2⁴/2⁸ = 2⁽³ˣ²⁾.2⁴/2⁸ = 2⁶.2⁴/2⁸ = 2⁽⁶⁺⁴⁾/2⁸ = 2¹⁰/2⁸ = 2⁽¹⁰⁻⁸⁾ = 2² = 4
